1) 3 + 3 + 4= 10

2) 2 + 2 + 9= 13

3) 1 + 1 + 36= 38

Let age of twins be x , and age of other child is y

now ;; (x^2)*y=36

factors of 36 are  :: 36*1 ;; 18*2 ;; 12*3 ;; 6*6 ;; 4*9;;

since x<y { twins are younger }  ;;;;; x==2 ;;;;;; y==9;;

Now house number == 2x+y = 4+9==13

Three children ages are 3,3,4

so her house number 3+3+4 =13

3+3+4=10 not 13

The children are of ages 4, 3 and 3
The product 4*3*3=36
The Sum 4+3+3 = 10

There are 3 possibilities
1) 1+ 1+ 36 ( we can neglect as this won't be their ages)
2) 2+ 2 + 9 ( in this case, lady can find easily)
3) 3 + 3 + 4 ( this maybe the ages since the lady has confusion)

mathematically this is incorrect question since there are 3 actully possible answers.

x+x+y=HN- this does nto add any value to problem solving.

xxy=36
1,1,36
2,2,9
3,3,6
